Rewiring Panasonic SD-200 Breadmaker

Re: Rewiring Panasonic SD-200 Breadmaker

Im interested to hear how that goes. Make sure that you get a motor that has enough grunt to stir the beans.

We got given our bread maker because it didnt work properly. Apparently it didnt always mix the dough enough. I think there is something a bit wrong with the motor, cause if we put more than 600g of green beans in, the motor cant handle it and stops.

What are u planning to power the motor by? Battery, Power pack? Just remember that 12v can still be dangerous if you get enough amps into it. :-)

Re: Rewiring Panasonic SD-200 Breadmaker

I just burnt out my SD200.  I had bypassed the entire circuit board, including the capacitor.  This worked ok for batches up to 450-500g, but you had to remember to give the paddle a spin as you switched it on.   I managed to keep it alive for a year (>50 roasts), but the inevitable happened...I plugged it in without realizing it was already switched on.  As I didnt spin the paddle to give it a kick-start, the motor burnt out.

Cried for a minute then pulled out a new breville big loaf I had on standby and never looked back.

Bad luck.

Is the new one a Smokey Deck 201?

Re: Rewiring Panasonic SD-200 Breadmaker

I am wondering if anybody has had a problem with the SD200 suddenly cutting out. I was roasting a batch of beans today and 13 and a half minutes into the roast the motor just stopped. I was forced to cool the beans probably about 3-4 mins shy of SC....not happy!!
I just turned it on again 10 mins later and it worked fine again. Has anybody else experienced this? I am wondering if there is a safety cut out if the motor gets too hot. This is the first time I have done two roasts quite close together - I would say I waited about 15 minutes after the first (which worked fine).

Hi Alistair,

Yes, we had this happen. We removed the thermal fuse from the circuit (although its probably wiser to leave the thermal fuse in circuit but tape it to the wall of the BM as far from the heat as possible - for safety), but there is a thermal cut-out somewhere in the motor circuitry itself (my guess). We also discovered this the hard way.

See this thread for our experiences:

FWIW, we no longer have this problem - even when weve done three roasts back-to-back. This is probably because we took the floor off the BM (cant remember why - to fix something or other) and never put it back on. Because we have a fan running over the whole setup, the BM motor must get a fair bit of ventilation.

Cheers
Stuart.

Thanks Stuart. I will try taking the floor off the BM and see if I still have a problem.

Cheers,

Same here.
Happened to me the first time I tried three back to back roasts.

Thundergod,

Did you solve the thermal cut out in the motor or did you take the bottom off too for ventilation?

Re: Rewiring Panasonic SD-200 Breadmaker

I havent needed to do three batches in a row since, so its not a problem now that Im aware of it.

For structural integrity I was planning to leave the bottom on and do what I did to my popper i.e. add more air holes.

Hi Alistair

Have your vacuum cleaner set up to blow not suck and as soon as it stops, blast the motherboard with air, it starts almost immediately. But dont have the top control panel/lid on the machine. See attached photo.


It never happens first batch always the one following, I always give it a cooling blast between batches. I have removed the thermostat thats all. Also plugged all holes from circuit board area to bowl area stopping hot air coming through.

Re: Rewiring Panasonic SD-200 Breadmaker

Interesting find! I had assumed that the motor itself had an inbuilt temp cut out but maybe its on the board?

I havent had the same problem again after taking the bottom of the BM off. I do however lay the BM on its side and let the fan blow on the motor in between saving the data from the roast on the computer and getting the next batch of beans ready - not sure if that is needed but cheap insurance! I will remember this advice in case it ever happens again - I have an air compressor close by.

I cant believe how much Ive gotten into this roasting - Just loving the coffee!! Every roast is as exciting as the first one....well almost!

Re: Rewiring Panasonic SD-200 Breadmaker

I also removed the heating element, but plugged all the holes between the two sections. It is surprising how much hot air was blowing directly on the circuit board.

If I get problems in the future I will remove the base as well, thanks.

Re: Rewiring Panasonic SD-200 Breadmaker

Guys it has been a while since my last post. I have just had a big attack of upgradeitis and bought a new machine and decided to give home roasting a try as well.

I pulled out the old Panasonic bm and I have re-wired it and I have removed the circuit board and I have de-soldered the capacitor and soldered the motor wires to it as needed.

So I now have no thermal cut off I assume but seeing as I will be watching the roast at all times I hope this should not be an issue.

I will let you all know how it goes.

Good decision barrel!!! -- you wont be able to go back to buying brown beans once youve had some successful roasts. :-) Ive also completely taken everything out of the BM in regards to circuitry. The only thing I left from the original BM circuit was the fuse. Should be fine (I guess) as our hasnt blown up or melted yet :-P However, we have a fan blowing across our entire roasting setting. Good for blowing away smoke, and keeping things cool.

I cant say this sure cause I havent pulled the motor appart, but Im pretty sure the motor must have a temperature cut out inbuilt. Weve had it cut out, even though all of the circuit boards have been pulled out and thrown in the bin ;-) Although, we havent had it cut out since taking the floor off though. Leaves it open for chaff, but I havent noticed that to become a problem yet.
